1 Claim. (Cl. 138-25) The; present. invention relates generally toimprovements inthe art of air conditioning, and relates moreparticularly to improvements in the construction and operation ofattachments for window type airconditioners.

A primary object of this invention is to provide an improved highlyefficient and economical conditioner attachment adapted to conduct anddistribute conditioned airfrom the conditioning unit to any desiredlocality remote therefrom.

Another. specific object of the invention is to provide an improved andexceedingly flexible low cost attachment for window air conditionerswhich may be readily applied without special tools to any existing unitsto conduct either a part or all of the conditioned air output to desiredlocalities Within the room or elsewhere.

Another specific object of my invention is to provide a novel andimproved air conditioner extender which may be readily fabricated ofsuitable plastic materials such as flexible sheets or extruded tubes ofpolyethylene and wherein conditioned air may be conducted to givenpoints through tubes of any desired lengths and number of sections.

Still another specific object of my present invention is to provide animproved conditioned air distributing device embodying an expansibleadaptor hood formed for quick and easy application over any-desiredportion or portions of the outflow or output section of commerciallyavailable window type air conditioners.

A further specific object of the present invention is to provide animproved air conditioner attachment comprising, a flexible hood havingan expansible mouth, means for securing the mouth' of'saidyhoodinposition over at least a portion of the air outlet of the airconditioning unit, and a flexible conduit communicating with theinterior of said hood for conducting air from said hood to a givenlocality remote from the conditioning unit.

These and other specific objects and advantages of the invention willbecome apparent from the following detailed description.

A clear conception of the features constituting my present improvements,and of the mode of constructing and of utilizing air conditionerattachments embodying the invention, may be had by referring to thedrawing accompanying and forming a part of this specification whereinlike reference characters designate the same or similar parts in theseveral views.

Fig. 1 is a perspective view of a typical air conditioner extenderembodying the invention and showing the same attached to a typicalwindow mounted air conditioning unit so as to cover the entire airoutlet thereof;

Fig. 2 is a somewhat enlarged fragmentary section through the mouthportion of the adaptor hood adjacent to one of the attachment suctioncups; and

Fig. 3 is another enlarged fragmentary section taken through theconnecting portions of adjacent tube sections and showing the samepartially uncoupled.

While the invention has been specifically shown and described herein asbeing particularly adapted for use with a window type air conditioningunit.having= a front.

wall air outlet and as embodying a particulartype of elastic-band in themouth ofithe hood which is shownin the drawingtas completely surroundingthe conditioned air outlet of the conditioning unit and securedto the.side walls thereof by a number of suction cups, it is not.

desired or intended to thereby unnecessarily limitthe scope or utilityof the improvement since the attachment: may be readily utilized oradapted for use with any type:. of conditioner with the hood beingrendered expansible by suitable-spring means or the like and beingretained; in position by any desired number: of suctioncups or, It isfurthermore contemplated;

other attachment means. that certain specific descriptive terms as usedherein shall be given the broadest possible interpretation consistentwith the disclosure.

Referring to the accompanying drawing, the reference numeral 5designates a typical 'air conditioning unit mounted in a window. 6 andhaving a front wall conditioned air outlet 7 and control knobs 8 on oneof the, side walls thereof; and the typical attachment shown therein asembodying the invention comprises, in general, a hood 10 formed offlexible plastic material such as polyethylene and having an expansiblemouth 11 at one end thereof and adischarge aperture 12 of fixed size atthe opposite end, the mouth 11 of the hood being rendered expansible byan elastic band 13 or the like sections 18 of polyethylene or the likecommunicating with the interior of the hood 10 through the aperture 12for conducting conditioned air from the outlet 7 through the hood 10 toany given locality remote from the con ditioning unit.

The hood 10 may be formed of a piece of sheet stock seamed byapplication of heat and pressure or it may, be extruded if desired, andwhile the tube sections 18 may likewise be fabricated of sheet materialsuitably.

seamed, it is preferable to form the same by extrusion as a matter ofconvenience. Similarly, although it has been found preferable to formthe expansible band 13 of rubber or other suitable elastic material, anexpansion spring, draw-string or the like may be substituted therefor,and any other suitable attachment means may likewise be utilized inplace of the suction cups 15 for securing the hood in position on theunit 5 with any number of such attachment elements being used for thispurpose to effect a reasonably good seal. To maintain an unobstructedopening permitting free flow of conditioned air from the hood 10 throughthe tube sections 18 while providing convenient means for quickly andeasily interconnecting the tubes 18 and the hood 10, the hood and tubesections may be provided with suitable relatively rigid cooperatingring-like coupling members 20, 21, the ring 20 of which has an annularexternal groove 22 and the ring 21 of which is of slightly largerdiameter so as to slip onto the ring 20 and is provided with an annularinternal flange or protrusion 23 adapted to interlock under slightcompression with the groove 22. These rings may be conveniently,although not necessarily, formed of a light weight and rust-proof metalsuch as aluminum with a ring 20 being applied to the hood so as toencircle the aperture 12 thereof and one of each of the rings 20, 21being applied to opposite ends of each tube section 18 to permitinterchangeable connections therebetween; and the respective rings mayPatented Feb. 25, 1958 be conveniently secured in position within foldedmarginal portions or heat-sealed hems 24, 25 respectively of the tubes18 or the hood 10 as the case may be as shown in Fig. 3.

From the foregoing detailed description, it is believed apparent thatthe present invention contemplates the provision of a novel and improvedhighly useful and eflicient attachment for air conditioning units bymeans of which conditioned air may be effectively conducted anddistributed as desired to any given locality remote from theconditioning unit. The improved devices may be economically fabricatedin quantity and at low cost from flexible plastic or like materials withthe aid of more-or-less standard bag-making equipment, and the devicesmay moreover be readily packaged and merchandised in relatively smalland easily handled units and may be quickly and properly assembled andapplied by a novice without the need for special tools or otherequipment. As hereinabove indicated, the mouth of the hood 10 may bereadily applied to the conditioner 5 so as to cover either all of theconditioned air outlet or only any desired portion thereof regardless ofwhether the air outlet 7 is located in the front wall or any other wallof the unit 5, and if the adaptor hood 10 should perchance cover anyswitch or other control, access thereto may be had by either stretchingthe expansible mouth or by reaching in through the aperture 12 beforecoupling the first tube section 18 by means of the rings 20, 21. Thetube sections 18 may, of course, be furnished in any desired lengths andwith any desired number of sections being supplied with a packaged unit,and while the coupling rings 20, 21 have been shown and described hereinas being of a particular construction, they may obviously beconsiderably modified as desired. The rings 20, 21 may likewise beformed of plastic or other materials instead of metal as indicated, anda suitable stand 26 may be provided for the free end of the last tubesection 18 as shown, the stand being readily attached as by a bolt 27 tothe ring or 21 as the case may be and permitting proper directionalcontrol of the air from the conduit. The plastic hood 10 and tubes 18may be quickly and easily mended, if torn, with the aid of availableadhesive tapes, and tests have proven that desired quantities ofconditioned air may be distributed to remote points in rooms other thanthat in which the conditioning unit is located with amazing efficiency.

It should of course be understood that it is not desired to limit thisinvention to the exact details of construction or to the precise mode ofuse herein shown and described, since various modifications within thescope of the appended claim may occur to persons skilled in the art towhich this invention pertains.
